To all whom it racy concern I Be it knownthat l, CLARENCE 'H. Donner, a citizen of. the United States, residing at Rock Island, in the county of Rock Island, and State of Illinois, have invented certainnew and useful Improvements in Nirker 'Mechanism for Planters, of which the fol lowing is a specification, reference being had therein to the accompanying drawing.

My invention relates moreparicularly to improvements in marker mechanismsof the disk type, and the object is to provide improved means for mounting the disk on the pole and for adjusting it. v

Of the accompanying drawings which illustrateonc embodiment of my inverdvion Figure l is a plan view of a planter having a marker mechanism embodying my invention; Fig. 2 is a front view of the planter the forwardv parts being omitted for the sake of clearness; Fig. 3 is a fragmentary sectional View through the marker pole and disk and the connecting devices.

Referring to the drawings 1 represents as a whole the planter frame which is mounted upon the ground wheels 2 2 and the axle 3. 4-4 are seedermechanisms mounted upon the frame in advance of the wheels.

5 is a marker pole carrying at its end a marker disk 6 rotatably-mounted at an angle to the pole axis. The inner end of the pole is pivotally secured to a rearward extending bracket 7, and a link 8 is provided for connecting the pole to the'frame at either side. The operator, by disconnecting the inner end of the link, can swing the pole from one side to the other and can then again fasten the link in place.

By referring to Fig. 3 it will be noted that the disk 6 is mounted on a journal casting or holder 9 which has an arm or bracket 10 extending along the poleat one side. A bolt- 11 passes through the pole and the arm and holds the casting in place. In order that the holder may be adjusted angularly on the pole to change the angle of the disk, a casting 12 is provided. This is. provided at 13 with a slot through which passes a bolt 14 for securing it in place. The end of the casting 12 is beveled at 15 and this beveled or wedge shaped. end can be inserted under the bracket 10 of the holder 9, the bolt 11 being loosened. By adjustingthe wedge casting 12 the angle of the disk can be changed, and when the desired adjustment Specification of Letters Patent.

is attained, the parts can be locked in place by means of the bolts; a

a it willbe observed that there are several holes for the. bolts 11 and 14. These make possible the adjustment of the marker longitudinally of the-pole.- These holes in the pole are uniformly spaced .so that any two adjacent ones can be used for receiving the two bolts 11 and' l l. 5

What I claim is: 1., In'a corn planter marking device, the combination of a non-rotatable pole straight from end to end, a non-rotatable disk holder having an inward projecting bracket open on. one side and extending along the ({QOIB, a concave-convex disk rotatably mounted on the holder and held thereby when in operation in fixed angular relation to the ground,

terposed between the bracket and the pole for varying the angle with respect to the pole at which the bracket and disk are held by the said fastening device. I

2. In a corn planter marking device, the combination of a non-rbtatable pole straight from end to end, a non-rotatable disk holder having an inward projecting bracket open on one side and extending along the pole, a concave-convex disk rotatably mounted on the holder and held thereby when in operation in fixed angular relation to the ground, a fastening device holding the bracket and disk in fixed relation to the pole axially and angularly, and a wedge interposed between the bracket and the pole and adjustable along the pole for varying the angle with respect to the pole at which the bracket and disk are held by thesaid fastening device.

3. In a corn planting marking device, the combination of a non rotatable pole straight from end to end and having three or more equally spaced transverse bolt holes therethrough near the outer end, a non-rotatable disk holder having an inward projecting bracket open on one side and gextending along the pole, a concavo-convexdisk rota tably mounted on the holder and held thereby when in operation in fixed an ular relation to the ground, a bolt adapts to extend through any of the aforesaid holes to peel-- tively hold the bracket and disk in fixed relation to the pole axially and angularly in any of several positions of longitudinal ad- ?atented June 8, 1915 Application filed-August s, 1913. Serial no. 783,424.

justment, a slotted Wedge adapted to be interpesed between the bracket and the pole bolt, and a second bolt adapted to extend 7 through the slot in the Wedge and the hole in the pole immediately adjacent the one In testimony whereof, I afiix my signature, in presence of two witnesses.
